Convert from auto_ptr to normal pointer

Question

I have some third party libraries that generate and return an auto_ptr. However, I really want to use some STL containers.

So I'm guessing one way would be to convert

auto_ptr <int> ptr = some_library_call ();

into a regular c++ pointer. Will the following work?

int* myptr = ptr;

If not, what is the best way to use STL with auto_ptr (yes I know it won't work directly... I'm aware that stl and auto_ptr don't mix together)?

Answer 1

你可以使用ptr.get()如果你想获得指针，然后让auto_ptr删除它，或者使用ptr.release()来获取指针并让auto_ptr忘记它（你必须删除它）然后。）

Answer 2

在auto_ptr上调用release（） ，然后可以将值存储在不同的智能指针或原始指针中，并将其与STL容器一起使用。
